APPARATUS FOR MAKING COPPER.

I To all whom it may concern:

Be it known that we, MARoEL ANDRii J UL- LIEN and EMILE LOUIS DEssoLLE,two citizens of the Republic of France, residing at Levallois-Perret, inFrance, have invented new and useful Improved A aratus for MakingCopper, of which the ollowing is a specification.

This invention relates to a method of rendering electrolytic copperabsolutely homogeneous, so that it has the same resistance and the sametensile strength in every direction.

This method chiefly consists in a polishing action efiected by means ofa suitable apparatus.

In the accompanying drawing given by way of example:Figure 1 is alongitudinal section of an apparatus suitable for carrying out theinvention, and Fig. 2 is a cross-section on the line 22 of Fig. 1.

The apparfius comprises a water-tight wooden case or vat a rovidedinside with two uprights b b on which rests the spindle c of a drum orcylinder d. At one en of the said spindle is mounted a kind of tappet orcam e, the projection f of which engages. with a recess in an arm 9mounted at the'end of a drivin shaft h which passes through one of thesi es of the vat a and is provided with a stufiing boxt' to preventleakage.

' The shaft h is provided with an outside driving pulley j for rotatingthe spindle h and consequently the cylinder (1.

Above the vat a is arranged a rolling track It on which can move acarriage l carrying a suitable electric or other motor m to the s indleto which is keyed a crank shaft-n.

he said crank shaft is connected by a rod 0 to an oscillating lever p,the pivot pin of which is su ported on the carriage Z. At the bottom enof the said-lever p isfarranged a polishing tool g adapted to be appliedagainst the cylinder with a suitable pressure.

The vat or contains as usual a suitable electrolytic bath, and thecopper is-deposited on the cylinder d, but, as it is being deposited,the carriage 1 moves longitudinally on its track k, the result of whichis the movement of the polisher g on the cylinder (1, while at the sametime the said polisher receives from the electric motor m areciprocating movement of suitable amplitu e. In moving along thecylinder (1, the polisher g describes Specification of Letters Patent.

therefore on the latter a screw-thread of a comparatively small pitch,but at the same,

time it describes in a continuous manner about the said screw a kind ofsinuous curve. I

curves intersect, and that no point of the metal surface produced on thecylinder d by the deposit 0 the electrolytic copper, escapes the actionof the olisher, the pressure of which on the oylin er is suitablydeter-' mined.

It will be seen from the fore oing that movement is imparted to the poisher in a manner to cause the same to move through or describe sinuousintersecting paths or in other words the polisher moves through aplurality, or in the embodiment shown, two prescribed courses, thebodily movement of the polisher and the other of which results from theindependent movement imparted thereto.

EX erience has shown that electrolytic deposit thus treated ac uires anabsolute such that the tensile strength and the resistance of' the.metal are the same in every direction, while in the metal obtained byordinary processes, the resistance is generally greater in the directionof the rotation than in the longitudinal direction.

The copper deposit thus treated can be used for making tubes, plates,etc. The metal thus obtained is much more suitable for the variousmachining operations than the electrolytic copper obtained by ordinaryprocesses.

In the accompanying drawing the polishing tool is shown applied to theupper portion of the cylinder (1, but it can also move on any generatriXof the said cylinder with the same results.

Having now particularly described and ascertained the nature of our saidinvention and in what manner the same is to be perform d, we declarethat what we claim is 1. An apparatus for polishing electrolytic coppercomprising a vat provided with a spindle carrying. the cylinder on whichthe metal is deposited, an outside shaft driving the spindle of the saidcylinder by means of a wooden tappet, a carriage arranged above the saidvat and moving longitudinally thereon, and carrying a motor operating,by

one of which results from means of a connectingrod and crank, anoscillating lever provided at its end with the polishing toolsubstantially as described.

2. An apparatus of the class described comprising in combination, areceptacle for the electrolytic bath, an actuated member on which themetal is deposited, a carriage movable with'respect to said member, apolisher carried by said carriage and bodily movable abreast of saidmember, and means for moving said polisher with respect to said memberindependently-of the bodily movement imparted to 1 said polisher.

3. An apparatus of the class described comprising. in combination, areceptacle for the electrolytic bath, an actuated member on which themetal is deposited, a carriage movable with respect to said member, apolisher carried by said carriage and bodily movable" abreast of saidmember, and means mounted on said carriage for imparting.

movement to said polisher independently of said bodily movement.

4; apparatus of the class described comprisingin combination, areceptacle for the electrolytic bath, an actuated member on Which themetal is deposited, a carriage movable-Withrespect to said member, apolisher pivotally'mounted on said carriage and bodily movable abreastof said member, and

means mounted on said carriage for imparting movement to said polisherabout its pivotal mounting.

5. An apparatus of 1 the class described comprisingin combination, areceptacle for the electrolytic bath, an actuated member on which saidmetal is deposited, a polisher engaging said member, and means forimparting movement to said polisher through a plurality of prescribedcourses so that the path described by said polisher will intersectthereby effecting continuous engagement of said polisher with theperipheral surface of said member.

6. An apparatus of the class described comprising 1n combination, areceptacle for the electrolytic bath, an actuated member.

on which the metal is deposited, a polisher engaging said member, andmeans-for imparting movement to said polisher to cause the sametodescribe smuous intersecting.
